I hate to sign up just to post once, but I can't help myself. Looking through this topic, I saw a lot of very interesting points, but one really stood out.
A couple of people (or maybe just one quoted repeatedly) have mentioned that rape games cannot be "justified". I think that's the core of the real misunderstanding on issues such as these. In America, content does not have to be justified to override censorship. Censorship has to be justified, and strongly so, to override the First Amendment. I know this sounds like an appeal to authority, but it's a pertinent authority and thus justified.
A very wise man named Steven den Beste said it best. "If I don't have the right to offend the neighbors, I don't have the right to free speech". No one is required by law to justify offensive communication, be it personal or commercial. They are required by law to justify harmful and false accusations - that's slander, or libel. They are required to justify dangerous speech, such as incitement to riot. If entertainment involves actually harming someone, the creators have to justify the actions they took which harmed that person or persons. But offensive material is automatically protected in this country, and I like it that way. Simply put, everything is offensive to someone. But censoring offensive material has tangible negative effects, while offense does not. Especially in the case of "opt-in" communication and material such as video games.
Whether or not someone wants to partake of such things is a personal decision. For some people, it is a moral decision. But their existence is not subject to anyone's approval, nor should it be.
Incidentally, I do not personally believe partaking in such entertainment is a moral decision. I'm not trying to couch it in euphemistic terms. The women depicted in these games are raped, often brutally. For the denizens of the game world, they are reduced from people to objects. That is a moral issue, and a despicable practice by any compassionate measure. But for humans playing the game, no such thing occurs. The women in rape games are not reduced from people to objects. They are not people, but simulations thereof.
Different people have different motivations for playing such games. Some undoubtedly play them, and enjoy them, because they would enjoy doing similar things to real women. I honestly think they are the minority, however. I find bondage to be arousing. I tend to enjoy depictions of consensual bondage play, but sometimes rape hentai can be enjoyable as well. I would never do such things to women in real life. On the contrary, I am literally nauseated by the idea of stripping someone of something as personal as their identity as a human. Make no mistake - that's what rape does. It happened to my wife, a few years before I met her, and I have had the good fortune to prevent it from happening to a college friend. When performed on real people, rape disgusts me. When performed on imaginary ones, it can be a pretext for arousing situations. Simple as that.
Posting this is probably a terrible idea, and most likely flame bait. But...none of these stances are hidden from the people I care about, and in that light it's difficult to take on-line insults seriously anyway. Flame away.
